Sure (untested and directly written in the web browser, as usual):
html span id: 'potsize'.
html textInput
onChange: (html updater
id: 'potsize';
callback: [ :h | h render: 999 ])
See SUFormTest has functional tests for all input elements. Similar
JQFormTest is the equivalent for JQuery. Unfortunately these tests are
a bit obscure, because I did not want to duplicate code across all
different form elements.
